SURGICAL BAKER.

Application filed March 4, 1926. Serial No. 92,232.

This invention relates to an improvement 'in' surgical bakers.

The object of the invention is to provide an improved form of surgicalbake-rs which 5 may be" used in hospitals 1n arthritis and rheumatismcases, where it is desirable to soften the tissues, and in connectionwith ointments and massagetreatments. The use of the baker is notconfined to such cases 1 but inay be used wherever it may be founddesirable.

. A further object of the invention is to P vide for tilting the baker.whenever it is used on a foot, or whenever it is desired to v 15''h'avez'one end of the baker higher than the other. in order to gaugethe heat for all of f thep'arts of the member. being treated.

these objects in view, the baker ineludes an outer casing which ispartially closed at the'opposite endsin order to receive the member fortreatment, and located along thetop ofthe casing are a pluralityofjelectric lamp sockets, which receive lamps, the latter extending inopposite directions from-the support in order to impart a moreuniform'supply of heat-to the member under itreatment. A reflector isplaced on the in- :side of the casing and behind the lamps, in

forder' to direct the heat therefrom toward and upon the-treated member.Supports 'are'providedon opposite sides of the casing Jinthe form ofbentwires which extend betweenthe'ca'sing and the reflector and which ythrough slots formed in a tilting disk 3 which. is pivot'allyconnectedfto the casing,

: but which is provided with means for securing the "same ina'fixedrelation relative tothe casing; VVhenever it is desired to tilt I thedevice the casing-is moved relative to 1 the wire 'supportsand about thepivot of the J'pivoting' disk, a.fte'r whi'ch it is lockedin its"itilted position.'- 1

V Inthe accompanying drawings F1g, 1 1s a s de elevation of theinvention;

2 isa longitudinal'section through thesame in-its tilted position andtaken on the line "2 -2 ofiFig. 3;

: Fig; 3isja transverse sectional view taken 1 on line 3 -3 of Fig."

; Fig.'4 is a 'perspective view ot the tilting Fig. 5 is a detailsect'onal view taken on jacket 1 but spaced therefrom to provide anintermediate space 6. The reflector 5 terminates at its top in adepressed socket support 7 ,which is provided with the inclined sides 8,whichextend upwardly in opposite directions as clearly shown in Fig. 3.Lamp sockets 9 are mounted in these inclined portions 8 for receivinglamps 10. By reason of the position of the lampsockets and the inclinedportions 8, it will be apparent that the lamps 10 will extend insubstantially opposite directions from each other and will therebyprovide a more uniform radiation of heat over and about the member beingtreated.

Connected with the lamp sockets 9 is an electric cable 11, which extendsthrough one end 2 of the baker and is provided with a suitable switch 12and plug 13 for supplying electric current to the electric lamps 10.

Mounted in the space '6, between the reflector 5 and the outer jacket 4,on each side of the baker. is apivot disk 14, which is provided with aperipheral flange 15 formed thereon, as clearly shown in Figs. tand 5.

The disk l l'has a central elongated slot 16 flange 15 and the outerjacket 1, as clearly shown in Fig. 5. Theflange 15 is provided with aplurality of notches 20 formed therein for receiving the upwardlyextending rods 21 of the wire support .22. This wire support 22 is madeof a single piece of wire bent back upon itself and having the ends bentupwardly, forming the rods 21 which pass through they pivot disk,. asclearly shown in Fig. 4. The rods 21 terminate at their upper ends inlugs. 23, which are adapted" to bear upon the back surfaces of thereflector 5, in order to support the outer ends of these rods.

In operation, the plug 18 is connected with a suitable source ofelectric current for illuminating the lamps when the device is placedover the member to be treated and these lamps will effectively supplyheat to the member under treatment, and due to the relation of the lampsto each other, they will heat the treated member on as many sides aspossible,'the reflector 5 serving to direct the heat about the treatedmember. The handle 24 is secured on top of the outer jacket 1 for'thepurpose of tilting the jacket with relation to the support and, in orderto accomplish this tilting operation, the wing-nuts 18 are loosened onthe bolts 17,- which releases the clamping connection between thesebolts 17 and the pivot disk 14 and also between the flange 15 and theback plate 19, which action allows the baker to be moved about the pivotbolts 17 into any adjusted position as for instance as shown in Fig. 2.

The slot l-fl'formed in the pivot disk 1 L serves to allow this disk tobe moved relative to the bolt 17, thereby permitting of the pivot actionbetween the -support-22 and the outer jacket 1 of the baker.

It will thus be seen that this improved form of bakeris both simple andinexpensive, while at the same time it is so constructed as toeffectively supply heat to the member under treatment and to allow thebaker to be moved relative to this member to supply a uniform amount ofheat to all parts thereof.

I claim:

1. A device of the character described including an arched outer casing,an arched reflector spaced from and within said outer casing, sidesupporting frames interposed between the reflector and easing, a pivot-Cl1Sk pivotally connected with the outer cas- ,ing and connected withthe supporting frame, and means for locking said pivot disk agamstpivotal movement.

2. A device of the character described including an arched outer casing,an arched reflector spaced from and within said outer casing, asupporting frame interposed between the reflector and casing, a pivotdisk flector and casing, a pivot disk for each of said supportingframes, said disk having a slot formed therein, a bolt extending throughsaid slot and through the casing tive to the casing.

for pivotally connecting the pivot disk to the casing, means for holdingthe pivot disk against pivotal movement relative to the casing, saidpivot disk having a flange formed on the periphery thereof and havingnotches formed in said flange for receiving the supporting frame, andlugs formed on the ends of the supporting frame for supporting theseends relative to the casing.

4. A surgical baker including an outer casing, a reflector spaced fromand within said casing, a lamp support mounted longitudinally of thecasing, and intermediate of the reflector, electric lamps extendinglaterally from the lamp support, a supportin frame interposed betweenthe reflector an casing, a pivot disk pivotally connected with the sidesof the casing and connected with the supporting frame, and means forlocking said pivot disk against pivotal movement.

5. A surgical baker including an outer casing, a reflector spaced fromand within said casing, a lamp supported centrally of the said casingand intermediate of the reflector, an electric lamp extending laterallyfrom the lamp support, a supporting frame interposed between thereflector and outer casing, and a pivot disk pivotally connected withthe casing, said pivot disk having a flange formed thereon and havingopenings provided in the flange for receiving the supporting frame andmeans for locking the pivot disk against pivotal movement relative tothe casing.

6. A device of the character described including a casing, a supportingframe therefor, a pivot disk pivotally connected with the casing, saidpivot disk having a flange formed thereon and having openings providedin the flange for receiving the supporting frame and means for lockingthe pivot disk against pivotal movement rela- 7. A device ofthe'character described including a casing, supporting frames for theopposite sides of the casing, a pivot disk for each of said supportingframes, said disk having a slot formed therein, a bolt extending throughsaid slot and through the C33! ing for pivotally connecting thepivotdisk to the casing, means for holding the pivot disk againstpivotal movement relative to the casing, said pivot disk haying a flangeformed on the periphery thereof and having notches formed in said flangefor receiving the supporting frame, and lugs formed on the ends of thesupporting frame for supporting these ends relative to the casing.

In testimony whereof I afiix my signature.
